The functional groups present in the filler can interact with the XIBOND™ Coupling agent to create optimal surface tension in the composite materials.

Coupling agents will improve the bonding between a polymer matrix and the filler surface; the addition of XIBOND™ is critical to achieve optimized properties in composite materials.

Composite materials consist of a polymer matrix in which fillers are dispersed. Typical fillers which are applied in the polymer processing industry are glass fibers, natural fibers and carbon fibers. These fibers are typically threated with a chemical substance to improve the affinity with the polymer matrix. The bonding in these composites systems can be further optimized with the addition of Coupling Agent to chemically bond the filler and the polymer matrix.

The XIBOND™ range offer coupling agents with a range of reactive compatibilizers containing functional styrenics with Maleic Anhydride (MA) functionality and Glycidyl methacrylate (GMA) functionality. The functional groups in the XIBOND™ coupling agent range can interact with the reactive groups such as -OH and -NH2 present in the filler. The interaction between the polymer matrix and the filler is dependent on the sizing or the end groups of the filler. Use the selector tool to find out which solutions the XIBOND™ portfolio has to offer.
